NPM

Controls nodes and dual nodes in a pre-defined way (start/restart, shutdown, control and monitoring of each node).

DNC (Dual Node Control)

Subcomponent of NPM. Allows two nodes, connected to the same LAN, to form a redundant configuration for fault tolerant applications by assigning states to these two nodes.

SCM

Offers a facility to monitor and control system technical status. Performs the acquisition of the following items:

 node, process and process group statuses controlled by NPM;

 dual node status, quality and item controlled by DNC;

 hardware status of devices;

 CDC datastore status;

 Link status (for one or several LANs);

 Global LAN status seen by local node;

 CPU load monitoring

 Application or UBSS error message.

SCM performs the acquisition of the following items:

System SNMP Agent(SSA)

• a SNMP agent to access UBSS

world

• Manages SNMP operations on

behalf of a supervisor (manager)

Time and Clock Management(TCM)

Provides functionalities regarding time and clock related aspects within a network-based system.

Input/Output Call(IOC)

A platform independent IO system to use printers, disks, file transfer.

Basic Name Server (BNS)

Find the physical location of logical communication endpoints;

Provides a fault-tolerant and distributed service based on CDC.

A fault-tolerant and distributed

service based on CDC;
